a. A maximum allowable extension not to exceed 25% of the surveillance interval, but

b. The combined time interval for any 3 consecutive surveillance intervals shall not exceed 3.25 times the specified surveillance interval.

4.0.3 Failure to perform a Surveillance Requirement within the specified time interval shall constitute a failure to meet the OPERABILITY requirements.for a Limiting Condition for Operation. Exceptions to.these requirements are stated

3.0.5 (Continued)

(as must be the components supplied by the emergency power source) and all i redundant systems, subsystems, trains, components and devices in the other i division must be OPERABLE, or likewise satisfy Specification 3.0.5 (i.e., be ,

capable of performing their design functions and have an emergency power source OPERABLE). In.other words, both emergency power sources 0 and 1A must be OPERABLE and all redundant systems, subsystems, trains, components and devices in both divisions must also be OPERABLE. If these conditions are not satisfied, action is required in accordance with this specification.

In OPERATIONAL CONDITION 4 or 5, Specification 3.0.5 is not applicable, and thus the individual ACTION statement for each applicable Limiting Condition .j for Operation in these OPERATIONAL CONDITIONS must be adhered to.

4.0.1 This specification provides that surveillance activities necessary to ensure the Limiting Conditions for Operation are met and will be performed .

during the OPERATIONAL C0NDITIONS or other conditions for which the Limiting Conditions for Operation are applicable. Provisions for additional surveillance activities to be performed without regard to the applicable OPERATIONAL CONDI-g TIONS or other conditions are provided in the individual Surveillance Require-j ments. Surveillance Requirements for Special Test Exceptions need only be performed when the Special Test Exception is being utilized as an exception to an individual specification.

4.0.2 The provisions of this specification provide allowable tolerances  :;

for. performing surveillance activities beyond those specified in the nominal surveillance interval. These tolerances are necessary to provide operational 1 flexibility because of scheduling and performance considerations. The phrase ]

"at least" associated with a surveillance frequency does not negate this (

allowable tolerance; instead, it permits the more frequent performance of H surveillance activities. [

The tolerance values, taken either individually or consecutively overN 3 test intervals, are sufficiently restrictive to ensure that the reliability associated with the surveillance activity is not significantly degraded beyond that obtained from the nominal specified interval, j N 4.0.3 The provisions of this specification set forth the criteria for determination of compliance with the OPERABILITY requirements of the Limiting Conditions for Operation. Under this criteria, equipment, systems or components are assumed to be OPERABLE if the associated surveillance activities have been satisfactorily perform d within the specified time interval. Nothing in this provision is to be construed as defining equipment, systems or components OPERABLE, when such items are found or known to be inoperable although still meeting the Surveillance Requirements.

AIIACHMENI_C SIGtHIlCANL11AZABMSlotlSIDJaAIlRH Commonwealth Edison has evaluated the proposed Technical Specification Amendment and determined that it does not represent a significant hazards consideration. Based on the criteria for defining a significant hazards consideration established in 10 CFR 50.92, operation of LaSalle County Units 1 and 2 in accordance with the proposed snendment will not:

I

1) Involve a significant increase in the probability or consequences of an accident previously evaluated because The 3.25 surveillance interval extension criteria of Technical Specification 4.0.2 was not considered in the plant accident analysis (UFSAR Chapter 15).

i

2) Create the possibility of a new or different kind of accident from any l accident previously evaluated because: 1 The surveillance interval will still be constrained by the 25 percent interval extension criteria of Technical Specification 4.0.2.

3) Involve a significant reduction in the margin of safety because: i Deletion of the requirement "any three consecutive intervals must not exceed 3.25 times the interval" will not significantly effect equipment reliability. This exemption will allow all surveillance intervals to be constrained by the maximum allowable extension of 25 percent of the specified surveillance interval which

• 11 enhance safety when used during plant operation. Normal scheu ting would still be at the specified surveillance interval.

Guidance has been provided in 51 FR 7744 for the application of standards to license change requests for determination of the existence of amendments which are and are not considered likely to involve significant j hazards considerations. This proposed unendment does nQt involve a i

significant relaxation of the criteria used to establish safety limits, a j significant relaxation of the bases for the limiting safety system settings, a I significant relaxation of the bases for the limiting conditions for operations.

Therefore, based on the guidance provided in the Federal Register and the criteria established in 10 CFR 50.92(e), the proposed change does not.

constitute a significant hazards consideration.
